I have been asked if i'm interested in doing a one off commercial job (inside and outside windows) and see how we go. It could also lead me to more commercial work if it goes well. Bear in mind i am a one man band, I had a look at this big office, there seem to be building work going inside, I am confident I can clean most windows but there is one massive window I think I will find difficult. I have uploaded a picture below the window i talking about. I can the outside massive window with wfp but it the inside I worried about, 1) I don't have a pole that big to clean the inside massive window 2) I will need to buy a wagtail (not sure which one) 3) there don't seem to be a lot of space to clean the inside because of the massive screen inside the building as you can see in the picture. I thinking of removing the brush from my water fed pole and use that to clean the inside and stick the wagtail & t bar on the pole to clean the inside windows. What u think?
